Fault finding – Replacement of components13B
REPLACING THE EGR VALVE (EXHAUST GAS RECIRCULATION VALVE)
After replacing the EGR valve, the computer must store the offset of the new valve (to 0 km), as well as the offset
measured at the time of the last engine cut-off (power-latch). With these data, the computer can detect clogging or
blocking of the EGR valve.
When the valve is replaced, clear the stored offsets so that the program uses the new valve’s offset value. The data
associated with this programming is combined under the EGR programming function.
Procedure to follow after replacement of the EGR valve:
– Select the CLEAR menu.
– Run fault clearing command RZ002 EGR adaptives,
– switch off the ignition,
–wait 30 seconds (auto-supply phase of the computer),
– start the vehicle to allow programming of the EGR valve,
– view parameters PR400 New EGR valve offset and PR129 Last EGR valve offset,
– if the reinitialisation was correctly performed then 0.6 V < PR400 = PR129 < 1.9 V.
REPLACEMENT OF PUMP, INJECTORS, RAIL + RAIL PRESSURE SENSOR OR COMPONENT OF THE LOW
PRESSURE CIRCUIT (DIESEL FILTER etc.).
After replacement of one of these components, carry out clearing using RZ004 Pressure regulation adaptives.
REPLACEMENT OF THE PARTICLE FILTER (Only Vdiag 45, 49, 4D)
After replacement of the particle filter, clear the fault DF308 Clogged particle filter if it is present or stored using
command RZ001 Fault memory. IMPORTANT
It is not possible to try an injection computer coming from the Parts Department because it will no longer be
possible to use it on another vehicle.
